Warning – Power Supply Voltage – Service Required. What shall I do?
In case KLANG:app shows a warning that the power supply of KLANG:vier or KLANG:fabrik needs to be checked. Please contact customer support and include a screenshot of the info screen. Email to firstname.lastname@example.org
In case the voltage is below 4.7V the unit requires service immediately.
For KLANG:fabrik, we recommend to use both power supplies for stability reasons.
